PATENT OFFICE ERWIN E. THURSTON, OF ROCHESTER, NEW YORK, ASSIGNOR TO UNITED STATES HOFFMAN MACHINERY CORPORATION, OF NEW YORK, N. Y., A. CORPORATION OF IDEAWABE GARMENT-PRESSING MACHINE Application filed February 24, 1925. Serial No. 11,115.

The present invention relates to garment pressing machines and more particularly to the type having a pressing element provided with a large steam chamber and a small steam chamber having a valved communication with the large steam chamber to receive steam therefrom, said small steam chamber being arranged Within the large steam chamber and provided with openings through which the pressing surface of the pressing element whereby the goods being pressed may be steamed. An object of this invention is to mount all the movable parts and parts subject to wear of the controlling valve between the steam chambers so that they may be readily reached for repair or replacement from the exterior of the two chambers,

To these and other ends, the invention consists of certain parts and combinations of parts, all of which will be hereinafter described; the novel features being pointed out in the appended claims.

In the drawings:

Fig. 1 is a vertical section throughthe pressing element withttlie presentinvention associated therewith;

Fig. 2 is-an enlarged section through the valve; and 1 Fig. 3 is a plan view of the valve.

Referring more particularly to the illustrated embodiment of the invention, 1 indicates the pressingelement, 2 indicates the enlarged chamber formed above said pressing element and receiving steam from a steam supply pipe 3. Arranged within the cham-. her 2 is a small chamber 4 separated from the chamber 2 by a partition 5. The pressing element 1 has openings 6 extending through its pressing surface and communieating with the interior of the chamber 4.

The feature of this invention is the provisionof a means which willpermit a valve arranged exteriorly of the chambers 2 and 4 to control the flow of steam from the chamber 2 to the chamber 4. In this instance, a valve casing 9 is formed with two chambers 8 and 11, separated by a'partition 19 formed with an ope 10. The chamber 8 con nects with the c amber 2 by a'passageway 7 and the chamber 11 connects with the course, when the ope will chamber 4 by a passageway 12. Preferably the two passageways 7 and 12 are formed in a cylindrical extension 13 on the valve casing 9, this extension 13 having its lower end screw threaded and engaged with the screw threaded walls of an opening 14 formed in the top of the chamber 4:. This cylindrical member 21 which by a helical spring 22 is pressed toward the seat 20. This spring surrounds the stem 23 of the valve member and abuts the rear face of the valve, its other end being in abutment with an internal shoulder 24 with a plug or cap 25 which closes an opening in the casing 9 v through which when the cap or plug is removed, the valve 21 may be passed. When the plug is removed the seat 20 will be exposed for reseating. 7

Movement of the valve 21 away from its seat may be effected in any suitable manner. In this instance, a plunger 26 is guided longitudinally in a bushing 27 removably fitted in the valvecasing and carrying a packing gland 28. One end of this plunger engages a socket 29 projected from the valve 21 while the other end is engaged by a U shaped memher or yoke 30, the arms of which are pivotally connected at 31 to lugs 32 extending downwardly from a lever 33 which is pivoted at 34 to a bracket arm 35 on the valve casing 9. 1

Depression of the lever 33 forces the plunger 26 inwardly to displace the valve 21 from its'seat 20 against the action of its spring 22 and, upon the release of the lever 33, the valve 21-reengagesthe seat to close the openin 10 between the two chambers 8 and 11. 0% 10 is opened, steam use from the chem r 2 to the chamber 4 an out throng}:5 the ports 6 to suppl steam to the material. ing pressed, and, w en the opening 10 is closed by the valve 21, the steam will be confined to the chamber 2. 7

From the foregoing it will be 1 seen that there has been provided in a pressing element I valve casing with the other chamber, a valve being arranged in the valve casing exteriorly of both chambers to control the flow of one passageway to the other. By this arrangement the movable valve parts are arranged to be reached exteriorly of both of the steam chambers without removing the valve casing. Furthermore, it is possible to utilize the steam pressure in the chamber 2 for maintaining the valve member closed and, as a consequence, a much lighter spring may be employed for giving the valve a tendency to move to closed position. As a result the amount of pressure required to open the valve is reduced to a minimum. This arrangement makes it possible to repair a pressing element of the type herein mentioned in a very short space of time, thus reducing-the loss through the occasion of the non-use of the pressing machine.

What I claim as my invention and desire .to secure by Letters Patent is:

1. The combination with a pressing element having two steam chambers, one of which is arranged above the other, said chambers having a common wall separating them, of a member connecting the top wall of the upper chamber and said common wall and provided with two passageways, one of which leads from the lower chamber upwards ly through said member and the other ofwhich leads from the upper chamber upwardly through said member, means providing communication between said passageways above said upper chamber, and a valve 'member controlling said communication.

2. The combination with a pressing element having two steam chambers, one of which is arranged above the other, and said chambers being separated by a common wall, the top of the upper chamber and the common separating wall having aligned openings, of a member extending through said openings and having a steam tight connection with the common wall and the top wall of the upper chamber, said member having two passageways, one of which leads through the low er end of the member upwardly and the other of which leads through the side-of said mem-v ber and in an upward direction, means arranged above the upper chamber and providing communication between said passageways above said'upper chamber, and a valve member controlling said communication.

3. The combination with a pressing element having two steam chambers, one of which is arranged above the other, and said chambers being separated b a common wall, the top of the upper cham er and the common separating wall having aligned openings, a member extending through said openings, and having a steam tight connection with the common wall and the top wall of the upper chamber, said member having two passageways, one of which leads through the lower end of the member upwardly and the other of which leads through the side of said member and in an upward direction, means arranged above the upper chamber and providing communication between the two passageways, and a valve member arranged to control such communication.
